They should run a marathon from Parramatta to Martin Place.

Call it "from the river to the CBD"

@MattHatton I think you underestimate just how long a marathon is. That is only just over a half marathon. You’d have to run back again to get it over 42.2km.
@mdreid I think you have taken this post a little too seriously.
@MattHatton I’ll have you know that interpreting jokes overly literally is no laughing matter!
